ALBERT J. KAUFMAN AND PORTER M. YOHE, OF NEW KENSINGTON, PENNSYLVANIA.

VENEERING-PRESS.

Specification of Letters Patent.

Patented July 13, 1909.

Application filed March 10, 1908. Serial No. 420,169.

To all whom it may concern:

Be it known that we, ALBERT J. KAUFMAN and Pou'rnu M. Yorin, citizens of the United States, residing at New Kensington, in the county of \Vestmoreland and State of Pennsylvania, hae invented certain new and useful Improvements in Veneering-Presses; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the characters of ref-erence marked thereon, which form apart of this specification.

This invention relates to an improvement in veneering presses, and it comprises a table having a series of parallel slots formed thereon, a series of clamps adjustable along said slots, means for making said clamps rigid with the said table, and the invention further consists in the certain details of construction and combination of parts, as will be fully described hereinafter.

In the accompanying drawings Fignre 1 is a plan view of our improved veneering press, showing several of the clamps in position. Fig. 2 is a front elevation of the same, a part of which is broken away. Fig. 3 is an enlarged plan view of one of the clamps removed from the table. Fig. 4 is a side elevation of the same. Fig. 5 is an end elevation of said clamp.

To put our invention into practice, and thereby provide a press whereby veneered wood may be bent and pressed into various curved or straight lines, we provide a table of a suitable size and form of construction, said table 1, comprising a platform formed with a series of parallel slots 2, extending its entire Width, each of said slots fitted with an open tube 3, in which a T headed bolt 4 is made to operate, said bolt being free to move the entire length of its slot, unless clamped by a thumbscrew 5. This bolt 4 is used for the purpose of fastening a clamp of peculiar construction to the table 1, the same passing through a slot 6, formed in a rearward extension 6 integral with the body-portion of said clamp. Forming a part of the clamp is an upwardly-extending member 7, having an open front and rear (8) and shouldered vertical opening extending its entire length, in which a square or oblong sliding member 9 is free to move up and down, said member 9 being formed with a threaded opening for the reception of a threaded shaft 10, having a thumb nut on its outer end, and a recessed inner end 11. This recessed inner end 11 of the threaded shaft engages in a shoulder slot 12 formed in movable clamp member 12, and serves to hold said member thereto. The inner end of the clamp is formed with an upright let, which forms the second member of the clamp proper, both members having rounded surfaces to contact with the material operated upon. A lug 15 with screw opening 16 is provided on the inner end of the clamp, by means of which said clamp may be attached to a wooden table or any extension or addition put thereto.

In operation a number of the abovcdescribed clamps are used, the number varying in accordance with the work to be done.

To form a semi-circular veneered arch for doorways, windows, &c., we provide a suitable strip of thin wood of a suitable length and Width, then scribe a semi-circular line 7), upon the table 1, as shown at Fig. 1 of the drawing. The clamps are now arranged in position to engage with their respective slots 2, the inner ends forming an approxin'late half circle. The moving member 12 of each clamp is moved forward by means of the screw shaft 10. The wood is now glued together and'placed between the clamp members 12 and 14 of each OliLl'l'lP, and the said screws 10 operated to place a pressure upon said wood. The clamps are now adjusted accurately in position with reference to the circle Z), and each clamp held rigidly in its correct position by its thumb screw 5. The work is allowed to remain in the press for several hours, or until the glue becomes thoroughly hardened, at which time the work may be removed from the press and will retain its bent shape.

It is obvious from the above description of the operation that any form of curve or even straight work may be done by the use of this press, as the clamps may be adjusted and set at any angle the one with the other to correspond with the character of the work.

Various slight modifications and changes may be made in the details of construction without 'departing from the spirit of the invention. Therefore we do not confine ourselves to the exact construction, shown and described, but wish to claim all such modified forms as would come properly within the general scope of the invention.

Having thus described our invention, what we claim and desire to secure by Letters Patent, is

1. A veneering press comprising a table formed with a series of slots, clamps secured in position by means of said slots, said clamps consisting of an upright stationary member, and a vertical horizontally-moving member, the one in line with the other, means for operating said horizontally-moving member toward and away from said stationary member and means for rigidly attaching said clamp to the table.

2. A veneering press comprising a table having on its top a series of parallel shouldered slots, clamps secured in position by means of said slots and bolts, said clamps comprising an upright stationary member
